This is how I watched the drama. I understand it is long, but I (personally) enjoyed it. I hope you do too.

• Season 1: Episode 1 until ~ 30.
  • Fuyao meets Wuji. This season can be broken into A (ep 1-16/17) and B (ep 16/17 -30).
• Season 2: Episode 31 until ~ 56.
  • I treated this as an A and B season as well, because Fuyao and the gang all enjoy side quests.You can stop watching around 47/48 and continue from there when you pick it up again. Quite a lot happens here. I don't remember most of it, but the battles were phenomenal.
• Season 3: Episode 57 until 66. 
  • The end.

If you're a binge'r of dramas and 66 episodes are child's play, then I hope you enjoy LoFY. However, if you're new to long dramas, feel free to use this blueprint as a way to ease yourself into things. Don't get overwhelmed and discouraged.
